DISCUSSION
TODAY THROUGH TUESDAY...
AS AN UPPER LOW SLIDES OVER SOUTHERN ALBERTA AND NORTHERN MONTANA
THIS MORNING, LOOK FOR THE CHANCE OF PRECIPITATION TO DIMINISH
UNTIL LATER TODAY WHEN THE LOW SLIDES FAR ENOUGH EAST TO BRING
PRECIPITATION BACK TO THE MOUNTAINS. IN THE MEANTIME, LOOK FOR
INCREASING WESTERLY SYNOPTIC WINDS ACROSS THE AREA. GUSTS IN THE
20S AND 40S MPH WILL BE COMMON ACROSS SOUTHERN MONTANA, WITH GUSTS
INTO THE LOW 50S MPH POSSIBLE OVER THE FOOTHILLS WEST OF BILLINGS.
TONIGHT INTO THURSDAY MORNING, THESE WINDY CONDITIONS WILL PERSIST
THROUGH THE MORNING HOURS, BEFORE SHIFTING EAST AND OUT OF THE
AREA THROUGH THE AFTERNOON/EVENING TIMEFRAME.
THE AFOREMENTIONED INCREASING CHANCE OF PRECIPITATION WILL COME IN
THE FORM OF SHOWERS AND WEAK THUNDERSTORMS, MAINLY ALONG AND SOUTH
OF INTERSTATE 90/94 WITH THE GREATEST CHANCE IN THE MOUNTAINS.
TONIGHT, A SHORTWAVE DROPS THROUGH THE REGION ON THE BACK SIDE OF
THE LOW, BRINGING A BETTER CHANCE OF PRECIPITATION ACROSS THE
AREA THROUGH THURSDAY MORNING. WHILE THE CHANCE IS LOW (5 TO 15
PERCENT), EMBEDDED THUNDER IS POSSIBLE.
SNOW LEVELS WILL BE AS LOW AS 7,000 FEET THIS MORNING, ALLOWING
LIGHT SNOW ACCUMULATIONS IN THE MOUNTAINS INTO THURSDAY. THE
PRIMARY ACCUMULATIONS WILL BE AT THE HIGHER ELEVATIONS OF THE
ABSAROKA/BEARTOOTH AND BIGHORN MOUNTAINS. THESE SHOWERS MAY
IMPACT MOUNTAIN RECREATION AND TRAVEL AT TIMES, INCLUDING THE
HIGHEST ELEVATIONS OF THE BEARTOOTH HIGHWAY IN THE BEARTOOTH
MOUNTAINS AND HIGHWAY 14 THROUGH THE BIGHORN MOUNTAINS.
WHILE CONDITIONS TREND DRIER AND WARMER FRIDAY, ENSEMBLE
FORECASTS SUGGEST ADDITIONAL WAVES OF ENERGY WILL DROP INTO THE
AREA FROM THE NORTHWEST THIS WEEKEND INTO EARLY NEXT WEEK,
BRINGING COOLER TEMPERATURES AND THE CHANCE OF PRECIPITATION BACK
TO THE AREA. LA/PM
AVIATION
ISOLATED SHOWERS EARLY TODAY WILL INCREASE IN COVERAGE TO
SCATTERED SHOWERS AND ISOLATED WEAK THUNDERSTORMS THIS AFTERNOON
AND EVENING. MOUNTAINS WILL BE FREQUENTLY OBSCURED IN RAIN/SNOW
SHOWERS (SNOW LEVELS AROUND 8000FT AGL) WHILE LOCAL/BRIEF MVFR IS
POSSIBLE WITH THE HEAVIER SHOWERS AT LOWER ELEVATIONS. SHOWERS ARE
LIKELY FROM KBIL EASTWARD LATE TONIGHT, AND DURING THIS TIME THERE
IS A GREATER CHANCE OF MVFR. THE RISK OF TS IMPACTING A TAF SITE
IS LOW, THUS NOT INCLUDED IN THE 06Z TAFS.
BRISK W-NW WINDS WILL CONTINUE THROUGH THE PERIOD. GUSTS 15-25KTS
TONIGHT WILL INCREASE TO 25-40KTS FROM MID MORNING TO EVENING. ALL
TAF SITES WILL BE IMPACTED BY GUSTY WINDS TODAY.
